JOHN GIBSON, J,R., OF ALBANY, NEW YORK.

Letters Patent No. 98,248, dated December 28,1869.

RAILROAD-CAR HEATER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, J om: GIBSON, J r., of the city and county of Albany, State of New York, have invented a new and improved Mode of \Va-rming Rooms of Cars or other Travel]ing-Oonveyanccs and Buildings; and I do hereby declare that the following is a full and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, in which Figure 1 is a perspective view of a car or room, with part of 1001 removed.

Figure 2 is a cross-section view through the centre of a car or room.

Figure 3 is a cross-section of warm-air chamber, under floor, withdeflector.

Figure 4 is a cross-section of warm-air chamber, with hooded registers.

The same letters indicate like parts.

The object of this invent-ion is to diffuse, in a perw fect manner, a modified, genial, and general warmth throughout the rooiiior rooms'of cars, or other travelling-conveyances and'buildings, (instead ofthe old way of warming them from certain points in the room, where the heat is-.intense,) .which is accomplished by conveying the heatfrom any suitable stove or heater, B, (placed below or outside of the car, conveyance, or room to be, heated,) into one or more chambers or spaces, a a, formed under the whole or part of the floor b, the floor itself forming the top of such' chamber, and the, lower sheathing (in a car) or ceiling c of an under room, forming the bottom, as shown in fig. 2. This floor b may be made of metal, either in whole or in part, either cast or struck up of sheetmetal, either fiat, arched, or corrugated, and-when corrugated, rests upon the sills d, .whieh form the sides of the chambers a a, and the heat is allowed to flow from one chamber to another, through its under corrugations c, fig. 2, in the manner indicated by arrows in fig. 1.

' When the floor is arched, the heat flows through its arches, and when flat, suitable openings are provided between the chambers a a to admit the free flow of heat from chamber to chamben. Suitable metal sheathing may be applied, where necessary, to protect the wood-work.

One or more registers may be placed under the seats, and each seat may be provided with a register, to, having a fixed hood, 2', or a register in the floor b, each provided with a flat or cone-shape deflector, 'h, or equivalent, at or near the line of the floor,

having a reversible hood, '5, which can bethrown either way, as-in fig 4, either of which will throw the heat across the floor. These hoods may alsoanswer for foot-rests.

Rooms with side seats, suchas lodge-rooms and street-cars, and the. like, may l/ave continuous registers o, fig. 1, or registers at intervals under the seats, thus being out of the way, a1 d yet giving out heat near the feet of the occupants; and these registers may also be provided with a fixed hood, i, or reversible hood, i, fig. 4.

All or any of these registers may be provided with pinchscrews r, fig. 1, or t-heirequivalents, for the purpose of holding the registers in a fixed position, when adjusted by the conductor, janitor, or proper person in charge. f

The smoke-pipe p can be conducted through any chamber a, or in any other direction, to'a suitable exit.

The advantages of this mode of warming, by constructing and arranging, as described, the various parts of the warmlug-apparatus, belonging and incidental to this invention, are these:

Firs:, .a modified, geui al, and even temperature of heat can be secured ii /every part ot'a room.

Second, the room can be quickly warmed, close to the door, by radiation from the floor itself, and the sprea'ding-opera-tion of the deflectors, or the hoods of the registers.

Third, by means of pinch-screws, or their equivalent, the registers are held secure, when set in any desired position, thus avoiding their unintentional displacement, and keeping their control more in the hands of the conductor, janitor, or proper person, than if said registers were not so fastened. r

Having described the principles of the construction and arrangement of the several parts of my invention, I do not claim the stoveor heater to be used, or its location.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The metallic floor b, corrugated, or otherwise, not perforated, in combination with the hot-air chambersa a, substantially as described, and-for the purposes set forth.

2. The adjustable deflector or warm-air spreader h, also its standard or support, in combination with any register, placed in the floor of any travelliugconveyance or room, substantially as set forth. and for the purposes described.

3. In combination with any warm-air register, a fired hood '5, or reversible hood 1?, for spreading the heat, substantially as described.

4. The pinch-screws 'r, or their equivalentflin combination with the registers a, substantially for the purpose set forth and described.
